Chris Paton writes: "The BBC reports that a British climber has set a world record by making a mobile phone call from the top of Mount Everest. The climber also claimed the record for sending the highest text message. The article goes on to say that the call and SMS were made possible by a base station set up by the Chinese, talking to a regular Motorola handset (albeit with the batteries strapped to the climber to keep them warm). With mobile phone coverage now available on Everest, is there anywhere that we are free from the seemingly unstoppable march of the mobile telephone?"
